I guess that would put you back in the primordial soup days before there was life. Hahah just kidding.
Anything before XP could be considered the stone age in computer years

Well, then, sir, one would have to distinguish the stages of primordial soup. In the 1950's I took a computer course at MIT on (among other machines) Whirlwind, a stored-program computer equipped with an assembler on which relocation had been already implemented but was considered too sophisticated for us students to use. In the 1960's I used a mainframe at Bell Labs for which the input was punched cards and the language was Fortran. In the 1970's I used Unix at Bell Labs. In the 1980's I wrote an accounting system for a nonprofit organization in C on a Unix machine, and learned how to use MS-DOS on a PC. Windows for Workgroups, a product of the 1990's with a graphical user interface, is quite advanced compared with these. I mean, any fool could tell WfW from an assembler with paper tape input, but could not so easily distinguish it from WinXP. In terms of time as well as technology, it's closer to XP than to Whirlwind. Please, sir, let us not forget our heritage.
